SI Sensitivity

(1197c SI Combo models only)

SI Sensitivity controls how much detail is shown on the display. Increasing the sensitivity shows more sonar returns from small baitfish and suspended debris in the water; however, the display may become too cluttered. When operating in very clear water or greater depths, increased sensitivity shows weaker returns that may be of interest. Decreasing the sensitivity eliminates the clutter from the display that is sometimes present in murky or muddy water. If SI Sensitivity is adjusted too low, the display may not show many sonar returns that could be fish.

To adjust the SI Sensitivity:

1.Highlight SI Sensitivity on the Side Imaging X-Press™ menu.

2.Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the SI Sensitivity setting. (Auto, 1 to 20, where Low = 1, High = 20, Default = 10)

SI Range

(1197c SI Combo models only)

SI Range sets the deepest range that will displayed in the Side Imaging views. The range must be set manually. The SI Range menu choice can only be accessed from the Side Imaging Views.

To adjust the SI Range:

1.From any Side Imaging View, highlight SI Range on the Side Imaging X-Press™ Menu.

2.Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the SI Range setting. (6 to 360 feet or 2 to 120 meters [International Models only], Default = 150 feet or 50 meters)

Chart Speed

(1197c SI Combo models only)

Chart Speed determines the speed at which the side sonar information moves down the display, and consequently the amount of detail shown. A faster speed shows more information in the Side Imaging Views and is preferred by most anglers; however, the sonar information moves across the display quickly. A slower speed keeps the information on the display longer, allowing you to see an entire area. Adjust Chart Speed to your personal preference.

To adjust the Chart Speed:

1.Highlight Chart Speed on the Side Imaging X-Press™ Menu.

2.Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the Chart Speed setting. (1- 9, Ultra, where 1 = Slow, 9 = Fast, Ultra = Fastest, Default = 5)
